MACHINE FORIVIAKING WIRE FENCING.

SPECIFICATION forming part of Letters Patent N o. 565,380, dated-August4:, 1896.

Application filed March 28, 1896. Serial No. 585,255. (No model.)

T0 all whom t may concern:

Be it known that I, WILLIAM EDENBORN, of the city of Chicago, Cookcounty, State of Illinois, have invented a certain new and usefulImprovement in Machines for Making Vire Fencing, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My present invention relates to an improved Inachine for making afencing consisting of longitudinal strands of wire provided with crimpsand tied together in pairs by transverse strands that are wound at theirends about two of the longitudinal strands, these transverse strandsbeing arranged in breakjoint fashion, those connecting the second andthird wires from the top of the fencing being located in the spacesbetween those connecting the two top wires, and so on down the fencing.

My machine is automatic in its operation, and produces the finishedarticle from coils of wire.

My invention consists infeatures of novelty hereinafter fully described,and pointed out in the claims.

Figure I is a top or plan view of my improved machine. Figs. II and IIIare enlarged detail transverse sections taken on line .II III, Fig. I,the dogs pivoted to the crosshead not being shown in Fig. II. Fig. IV isa top view of the crimping-dogs in open position. Fig. V is a top viewof the crimpingdogs closed. Fig. VI is a side elevation. Fig. VII is anenlarged vertical transverse section taken on line VII VII, Fig. I.Figs. VIII, IX, and X are diagrams illustrating the operation of thecoiling-spindles. Fig. XI is a detail top view of same. detail verticalsection taken on line XII XII, Fig. I, looking in the direction of thearrow A. Fig. XIII is a similar view taken on line XII XIII, Fig. I,looking in the direction of the arrow B. Fig. XIV is a diagram showing asection of the fencing made by my improved machine. Fig. XV is anenlarged transverse section taken on line XV XV, Fig. XIII. Fig. XVI isa side view of a series of rollers to straighten the wire from which thetransverse wires are cut before it enters the Ina- Fig. XII is anenlarged chine. Fig. XVII represents a modification of the means forfeeding the strand-wires.

Referring to the drawings, 1 represents a 8 represents a long rackconnected to the crank 7 by means of a pitman 9. This rack lies beneathand meshes into anumber of pinions 10, formed upon or secured to sleeves11, l(see Figs. I and VIL) these sleeves being supported by a bracket orstand 12, secured to the bed-plate l, and in which the sleeves arejournaled, this bracket also serving to support the rack 8, as shown inFig. VII. It will be observed that as the rack is moved back and forthby the crank-shaft 7 there will be imparted to the sleeves 11 aback-and-forth rotary movement.

Within each sleeve 11 is a spindle 13, having an eccentrically-arrangedfinger orpin 14, the inner end of the pin fitting in the head 15 of thespindle, as clearly shown in Fig. VII. The spindles are loose within thesleeves and are caused to turn therewith by virtue of the pins 14passing through caps or heads 16, secured to the sleeves by screws 17 orotherwise.

1S represents the strand or longitudinal wires of the fencing. There isa spindle 13 for each strand-wire, and each wire passes through acentral perforation in the head l5 of its spindle and also through aperforation in the cap 16. As stated, the spindles 13 iit loosely withintheir sleeves, and they have end movement therein, so as to cause theiingers 14. to be rotru ledirommhenfgtce of the cap 16 at me proper timeand then to cause the fingers 12F torecedemntil their outer ends aresubstantially flush with the outer faces of the caps. This end movementis imparted to the spindles 13 by means of bell-crank levers 19,fu-lcrumed on a rod 20. The upper ends of the levers are provided withyokes 21, fitting in grooves 22 in the ends of the The levers areoperated to respindles 13.

IOO

tract the spindles by means of the cams 23 on the shaft 3, and thelevers are moved in the other direction to cause the fingers 14 to beprotruded by means of springs 24.

The strandwires are fed forward intermittently by passing betweenrollers 25 and 26, (see Figs. I and VI,) set-screws 27 being providedfor the purpose of causing the upper roller to bear with more or lesspressure upon the lower roller. The lower roller 26 is provided with apinion 28, engaged by a pinion 29, meshing into a pinion 30 on the shaft3. The shaft 3 is provided with a gear-wheel 31, engaging a pinion 32 ona driving-shaft 34, provided with a pulley 35. The pinion 30 may betermed a mutilated pinion, that is to say, two of its sides or quartersare provided with eogs, and the other two sides or quarters have nocogs, the result of which is that the roller 26 is moved intermittently.XVhen the cogs of the pinion 30 engage the pinion 29, the roller 26 willbe turned, and then while the cogless portions of the pinion 30 arepassing the pinion 29 the roller 26 will remain idle. This results inthe strand-wires receiving an intermittent movement and allows them toremain stationary while the transverse wires are being wrapped about thestrand-wires.

In Fig. XVII, I have shown a modification of the mechanism for impartingan intermittent movement to the strand-wires, in which the roller 26 isprovided with a ratchet-wheel 36, engaged by a pawl 37 on a sliding bar38, supported by a lug 39 on the housing 40 of the rollers 25 and 26.This bar 38 is connected to an extension 41 on a ring 42, that fits overan eccentric 43 on the shaft 3. As the parts move from the positionshown in full lines, FiO'. XVII, to the position shown in dotted linesthe roller 26 is turned and remains idle while the parts are moving backfrom the position shown in dotted lines to the position shown in fulllines.

44 and 45 represent the transverse `wires. The fencing shown in Fig. XIVcomprises eight strand-wires- When this number of strand-wires is used,it requires seven transverse wires to connect the strand-wires. Itrequires four of these transverse wires to connect the first and second,the third and fourth, the fifth and sixth, and the seventh and eighthstrand-wires together, and it requires three to connect the second andthird, the fourth and fifth, and the sixth and seventh strand-wires. Thefirst set of Vwires is indicated at 45, and the second setat 44, Figs.XII and XIII. These wires are fed forward intermittently, time beinggiven after they are fed forward for the transverse wires to be cut, andfor the fingers 14 to wrap their ends about two of the strandavires,land also for the strand-wires to be moved forward again after thewrapping and the cutting of the transverse Wires. This `intermittentmovement of the transverse wires is effected by a head 46 for the wires44 and a head 47 for To prevent the wires being carried back by theheads, one of the standards 49 is provided with dogs 50a, that do notinterfere with the forward movement of the wires, but prevent the wiresfrom moving backward.

The heads 46 and 47 are moved by means of levers 51 and 52, (see Fig.I,) pivoted at 53 to the bed-plate, their inner ends being pivoted tothe heads 46 and 47, respectively, and their outer ends being engaged bya cam 54 on the shaft 3. It will thus be seen that as the shaft 3 isturned the heads 46 and 47 will be moved, and that the head 46 will moveforward while the head 47 is moving' backward, and vice versa, and theparts are so disposed that first one set and then the other set of thewires 44 45 are fed forward, and each set `is fed forward at the propertime.

As the transverse wires are fed forward they are guided so that eachwill pass over one and under the other of two of the strandwires, asseen in Fig. XII. This guiding of the transverse wires is effected bytwo levers 55 and 56, pivoted, respectively, at 57 and 58 to a standard59. To the levers are secured guide tubes or boxes 60, one for each.transverse wire. (See Figs. XIII and XV.) The tubes are so arranged onthe levers 55 and 56 as to cause the transverse wires to be projected inthe proper direction to cause them to be fed to the strand-wires asstated. Secured to the levers 55 and 56, close up against the ends ofthe tubes 60, are knives or cutters 61,that operate in conjunction withstationary knives or cutters 62, made fast to the bracket or standard12, (see Fig. XII,) to sever the transverse wires, the levers 55 and 56being moved for this purpose by means of a cam 63 on a shaft 64, (seeFigs. I and XIIL) the shaft 64 being journaled in boxes 65 and havingbevel-gear connection 66 with the shaft 67, j ournaled in boxes 68, theother end of the shaft 67 having a bevel-gear `connection 69 with `theshaft 5.

The cam 63 is so formed as to cause the levers 55 and 56 to be movedimmediately after the transverse Wires move forward, the movement of thelevers effecting the cutting of the transverse Wires into properlengths. As these wires are out the spindles 13 move endwise, protrudingthe fingers 14, so as to bring them into a position that will cause themto engage the transverse Wires as the spindles revolve, one fingerengaging beneath one end of each transverse wire and another fingerengaging the otherend of this transverse wire from above. As thespindles revolve .the fingers wrap the transverse wires about thestrand-Wires, as shown in Figs. VIII to XI, inclusive, and as thewrapping progresses the fingers are gradually with- IOO IIO

drawn by the retraction of the spindles 13, and just at the time thewrapping is completed the fingers 14 finally leave the wires, thiscondition of the parts being represented in Fig. XI.

As the fencing is formed it is taken up and moved along intermittently.I do this by the use of a mechanism that will form crimps (see Fig. XIV)in the strand-wires to provide for expansion and contraction of thefencing when in service without danger of the strand-wires being broken.The mechanism that I have shown for thus taking up the fencing as it ismade, and also for forming crimps in the strand-wires, is represented inFigs. I to V, inclusive, and consists of a cross-head 70, held in guides71, secured to the bed-plate of the machine, and which carries a slide72. The slide 72 is capable of moving endwise with relation to thecrosshead, and it carries a number of dogs 73, pivoted at 74 to theslide above the cross-head. The strand-wires are shown in dotted linesin Figs. I, II, and III, and also in Fig. VI, and there is a dog 73 foreach strand-wire.

75 represents dogs pivoted at 7 G to the upper face of the cross-head.There is a pairv of these dogs for each dog 73, as shown in Fig. I.Beneath thev cross-head is a plate 77, that has oblique slots 78, inwhich fit pins 7 9, projecting from the under face of the slide 72. Theplate 77 is connected by links S0 to cranks 81 on a rock-shaft 82,secured to the bed-plate 1 bymeans of boxes S3. The shaft 82 has a crankS4, connected b y a rod 85 to an eccentrically-located wrist-pin S6 onthe wheel 31. (See Figs. I and VI.) As the wheel 31 revolves it impartsa rocking movement to the shaft 82, causing the movement of thecross-head 70, and the parts which it carries, back and forth in thedirection of the length of the strand-wires.

87 represents a dog pivoted to one of the guides 71 (see Fig. I) andwhich is capable of moving only in the direction of the arrow. WVhen thecross-head 7 O is in its rear or inner position, (shown in Fig. I,) andbefore the rock-shaft 82 commences to move the plate 7 7, the end of theslide 72 is behind the dog S7. )Vhen the rock-shaft commences to movethe plate 77, the cross-head 70 is held from forward movement until theslide 72 moves out from behind the dog S7. The slide is thus moved outfrom behind the dog 87 by means of the pins 79 on the slide fitting inthe oblique slots 7S in the plate 7 7 and this end movement of the slidecauses the dogs 73 to move from the position shown in Fig. IV to theposition shown in Fig. V, thus crimping the strand-wires between themovable dogs 73 and the xed dogs 75. By the time that the end of theslide passes the end of the dog 87 (in which position it is shown inFig. I) the wires have been fully crimped, and now the further turningof the shaft 82 pulls the cross-head 70 with the parts attached to it inthe direction of the dotted arrow,

Fig. I, and the fencing is thus moved forward or taken up the distanceapart of the transverse wires. When the fencing has been moved thisdistance, the shaft 82 rocks in the other direction, and the firstaction of the plate 77 is to move the slide 72 back, thus releasing thestrand-wires by pulling the dogs 73 away from them, or from the positionshown in Fig. V to the position shown in Fig. IV. The further movementof the shaft 82 in this direction carries the cross-head 70, with theparts that are attached to it, back to their inner position, and as theparts move back the dog S7 yields when pressed against by the slide, andas soon' as the slide passes the dog springs back into the positionshown in Fig. I, so that the next time the shaft 82 rocks forward thedog will keep the crosshead from moving until the slide has movedendwise to crimp the wires, as explained.

As stated, the dogs 7 3 and 75 are pivoted to their supports, so that asthe cross-head moves back these dogs will turn on their pivots if theycome against the transverse wires of the fencing, so as to pass underthese transverse wires, and will then automatically assume an uprightposition.

It is evident that the mechanism shown and described for crimping andtaking up the fencing may be depended upon to produce the forwardmovement of the strandwires,- instead of using the feed-rollers, inwhich case the feed-rollers would stillbe useful to maintain a tensionon the strand-wires and keep them taut at the point of application ofthe transverse wires.

The wires from which the transverse wires are cut would ordinarily betaken from a reel, and it is desirable to have the natural ICO coiltaken out of these wires before they are v fed, and this may be done byan ordinary system of straightening-rolls, such as is shown in Fig. XVI.
